Investors are gaga for BABA. Alibaba(BABA, Tech30), the giant Chinese e-commerce company, went public in September and immediately became one of the most popular stocks to track.

It makes sense. The stock surged on its first day of trading and was the biggest IPO of all time. Even though the stock has pulled back lately due to concerns about earnings growth, Alibaba is still worth more than Facebook(FB, Tech30), eBay(EBAY, Tech30) and Amazon(AMZN, Tech30).
